web application with drag drop and change fascility

Hi All,

not sure if ist the right place.

We have a requirement in Org Mangement to offer a web application to the users in which they must be able to

1. drag and drop the Business Partners from one Position to the other Position

2. Change the percentage of this assignement.

Is it possible to develop in Web dynpro or in FPM. if not what could be the alternative.

Thanks
